The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Application of a Database-Independent Approach To Assess the Quality of Operational Taxonomic Unit Picking Methods

mSystems, 2016
Assignment of 16S rRNA gene sequences to operational taxonomic units (OTUs) allows microbial ecologists to overcome the inconsistencies and biases within bacterial taxonomy and provides a strategy for clustering similar sequences that do not have ...

Escherichia coli O157:H7 in Malta for the first time [PDF]

, 1996
The emergence of E coli O157:H7 in Malta is a sign of the times. It represents one of the newly emerging infections associated with food. The first two documented cases of E coli 0157:H7 infection in Malta occurred in July and August, 1996.

Heterogeneity in Surface Sensing Suggests a Division of Labor in Pseudomonas aeruginosa Populations [PDF]

, 2019
The second messenger signaling molecule cyclic diguanylate monophosphate (c-di-GMP) drives the transition between planktonic and biofilm growth in many bacterial species.

Molecular characterisation of human penile carcinoma and generation of paired epithelial primary cell lines

Molecular Oncology, EarlyView.
Generation of two normal and tumour (cancerous) paired human cell lines using an established tissue culture technique and their characterisation is described. Cell lines were characterised at cellular, protein, chromosome and gene expression levels and for HPV status.

A Systematic Approach to Promote Environmental Engineering Students' Learning in Environmental Molecular Microbiology

Journal of Microbiology & Biology Education, 2021
Environmental Molecular Microbiology (EMM) is a core course cluster for students majoring in environmental engineering. To help students learn the EMM courses, we developed a three-stage teaching approach to deliver EMM courses in a systematic manner ...

Primer selection impacts specific population abundances but not community dynamics in a monthly time-series 16S rRNA gene amplicon analysis of coastal marine bacterioplankton. [PDF]

, 2018
Primers targeting the 16S small subunit ribosomal RNA marker gene, used to characterize bacterial and archaeal communities, have recently been re-evaluated for marine planktonic habitats.

Evolutionary dynamics of the chloroplast genome in Daphne (Thymelaeaceae): comparative analysis with related genera and insights into phylogenetics

FEBS Open Bio, EarlyView.
Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...
